He didn't get the memo

I've been having trouble updating the page siloen.html for the last week. I update the picture and links in Dreamweaver and upload, but I'm still seeing the old version of the page, even after hitting reload. I was able to get around it before by logging onto the webhost and deleting the page entirely, then uploading from Dreamweaver, but that isn't working today. Still seeing page 4 when I KNOW 5 ought to be showing.

I took siloen.html down for 20 minutes, and when I loaded it after that it was correct. I also cleared my cache. I don't think that's the problem, but it was worth a try.

This isn't happening with any other page on the website.
